使用前准备:
使用前,请将 Endo F1 试剂取出,4℃或者冰上解冻,10000rpm 离心 10 秒,确保所有试剂都在管底。
反应试剂:将-20℃储存的 10×Glycoprotein Denaturing Buffer 缓冲液、10×GlycoBuffer 2 及 10%NP-40 溶液取出,待用。
注意:根据实验需要,准备相应的试剂,如非变性条件下进行去糖基化反应,不需要准备 10×Denaturing缓冲液及 10% NP-40 溶液。
使用方法:
变性条件下糖蛋白去糖基化
1、用去离子水溶解 1-20 µg 的糖蛋白,加入 1 µl 的 10×Glycoprotein Denaturing Buffer,用去离子水定容到10 µl;
2、75℃孵育 10 min;
3、加入 2 µl 的 500 mM Sodium acetate pH5.5,2 µl 的 10% NP-40,轻轻吹打混匀;
4、加入 1-4 µl 的 Endo F1,加去离子水到 20 µl,轻轻吹打混匀;
5、37℃孵育 1-4hr;
6、用于 SDS-PAGE 分析或 HPLC 分析。
非变性条件下糖蛋白去糖基化
1、取10-100µg 糖蛋白溶液,加入 2µl 500 mM Sodium acetate pH5.5,2-5µl Endo F1 ,补加纯化水使得反应体系总体积为 20µl,轻柔混匀;
2、37℃ 条件下反应 4-24hr。
注意:当对天然糖蛋白去糖基化时,建议将等量糖蛋白样品进行变性后再同步进行酶切实验作为阳性对照,以确定非变性条件下去糖基化反应的程度。
【注】体系放大时候,孵育时间或酶量需要根据实际情况调整,可低速震荡混匀,可以增加转化率。

Endo F1 is a highly specific recombinant endoglycosidase expressed in Escherichia coli. Its gene originates from Elizabethkingia miricola. It specifically cleaves core-fucose-free high-mannose and hybrid-type N-glycans from glycoproteins. This product boasts high enzymatic activity and excellent stability, and is applicable to the modification and analysis of antibody glycosylation.

Pre-experiment Preparation
Before use, take out the Endo F1 reagent, thaw it at 4°C or on ice, then centrifuge at 10,000 rpm for 10 seconds to ensure all liquid collects at the bottom of the tube.
Reaction Reagents: Take out Endo-β-N-acetylglucosaminidase F1, 10× Glycoprotein Denaturing Buffer, 10× GlycoBuffer 2 and 10% NP-40 solution stored at -20°C for later use.
Note: Prepare reagents according to experimental requirements. If deglycosylation is carried out under non-denaturing conditions, 10× Denaturing Buffer and 10% NP-40 solution are not required.
Operating Procedures
Glycoprotein Deglycosylation under Denaturing Conditions
1. Dissolve 1–20 µg glycoprotein in deionized water, add 1 µL of 10× Glycoprotein Denaturing Buffer, and adjust the volume to 10 µL with deionized water.
2. Incubate at 75°C for 10 min.
3. Add 2 µL of 500 mM Sodium Acetate (pH 5.5) and 2 µL of 10% NP-40, then mix gently by pipetting.
4. Add 1–4 µL Endo F1, top up to 20 µL with deionized water and mix gently by pipetting.
5. Incubate at 37°C for 1–4 hr.
6. The reaction product can be analyzed by SDS-PAGE or HPLC.
Glycoprotein Deglycosylation under Non-denaturing Conditions
1. Transfer glycoprotein solution containing 10–100 µg target protein, add 2 µL of 500 mM Sodium Acetate (pH 5.5) and 2–5 µL Endo F1. Add purified water to a total reaction volume of 20 µL and mix gently.
2. Incubate the mixture at 37°C for 4–24 hr.
Note: For deglycosylation of native glycoproteins, it is recommended to digest an equal amount of denatured sample in parallel as a positive control to assess the extent of deglycosylation under non-denaturing conditions.Remark: When scaling up the reaction system, adjust incubation time or enzyme dosage accordingly. Gentle low-speed shaking can improve digestion efficiency.
